WinSCP does not work with Google or even with Oracle

Good morning,
I wanted to report a WinSCP bug on Windows 10 system. I can't connect to Google and Oracle cloud services.
I started a long discussion here:
Collegarsi al server con WinSCP e file .ppk • Forum Ubuntu-it
but it remained without solution and the verdict is a WinSCP problem.
Thank you

You probably need to use WinSCP 5.20.x:
Issue 1952 – Support rsa-sha2-256 and rsa-sha2-512 SSH public key algorithms

@Guest: OCI Object Storage works with WinSCP GUI fine. When setting up the connection do the following:

• Use the S3 compatible endpoint with port 443:
  {object-storage-namespace}.compat.objectstorage.{region}.oraclecloud.com
  
• Click the "Advanced" button
  Set the region again here
  Set the URL style to Path
  

You should be able to view objects, upload/ download objects. Used it today.

I have documented how to access Oracle Object Storage:
